Vocabulary Terms A vertex is a point where two sides of a polyhedron meet or a point opposite the base of a cone. Vertex
How many nets do you think you can come up with to form a cube? There are exactly eleven nets that will form a cube.
triangles Nets for Pyramids have one base and lots of triangles. Sometimes they look like stars. base base

Fun with Prisms
Vocabulary Terms FACE Prism – a A cylinder with polygons for bases (faces). All prisms are special cases of cylinders. FACE
Vocabulary Terms BASE In a prism, these faces are called bases. You name a prism by the shape of its bases. BASE
Triangular Prism Vertices 6 Edges 9 Faces 5 The base has 3 sides.
Rectangular Prism The base has 4 sides. Vertices 8 Edges 12 Faces 6
Pentagonal Prism The base has 5 sides. Vertices 10 Edges 15 Faces 7

Special 3-D Shapes Cylinder Sphere Cone
Sphere Every point on the surface of the sphere is the same distance from the center The normal definitions of faces, edges and vertices are not appropriate for a sphere.
Cone The vertex of the cone is opposite the circular base of a cone. The cone has a face, a vertex, and an edge (formed by the base and the lateral face).
Cylinder A prism with two congruent, parallel faces called bases. A cylinder has 2 faces (circular bases), edges and no vertices.
